I know stuff all about selling, but I do have a lot of reps from printers after me.
From any printer, I want a quiet life and a good price. If you can’t achieve a Delta-E of 2.5 or less on everything that leaves your premises (or can’t convince me that you can!), it’s not happening.
Beyond that, it’s all about how you can add value. This can mean having a basic design studio to update and modify artwork when needed. If you’re flexo, that means a good pre-press setup with CTP and proofing abilities that will save me giving a pre-press house £££. Litho, it means someone who can provide good technical advice – often this will be as simple as sense checking a design to make sure a printer in China with an ancient press has any shot at achieving it. If you have your own plant in other countries, then even better.
If you’ve not got any of the value added abilities, then it’s going to be a much harder sell.
As a technical bloke, the key thing is making sure you have the people skills to make it fly – presumably your boss thinks you have the skills if he’s keen for you to do it.
